SATURATOR.

Application filed April 19, 1923.

This invention relates to a device for saturating objects with liquid or semi-liquid materials. By this invention ob ects or materials thatare capable of absorbing liquid saturating or waterproofing materials can be immersed in the liquid material to the desired depth and for the desired length of time, and a series of such objects can be immersed for equal lengths of time thereby assuring uniforinity of saturation of the same.

This invention is particularly adapted for saturating samples of roofing felt, which samples should be immersed for predetermined lengths of time in an oil bath or the like for the purpose of testing the saturating qual ties of the samples, although the invention is not restricted to this use as other objects that are to be saturated or waterproofed can in like manner be passed through saturat ng or waterproofing materials such as oil, bituminous materials, melted tallow, waxes, rosins, etc.

The invention Will be understood from the description in connection with the accompanying drawings, in which Fig. l is a side view of the device;

Fig. 2 is a section along the line a-a of Fig. 1;

Fig. 3 is a detail of part of the drive mechanism;

Fig. 4 is a side view of the carrier; and

Fig. 5 is a perspective view of the same.

In the drawings, reference character 1 1ndicates a tank for containing saturating or waterproofing materials which tank is provided with a heating coil 2 through which hot fluids may be passed for keeping the saturating material in the liquid state. A framework comprising upright pieces 3 and cross-pieces 4 is set in the tank 1. This framework is adjustable along the guides 5 which rest upon the bottom of the tank 1. The framework may be caused to extend to different depths in the tank by means of pins 6 which pass through holes 7 in the crosspieces 4 and guides 5 thereby holding the framework in adjustable positions on the guides. Straps 8 on cross-pieces 4 retain the guides 5 in position.

The framework carries two sets of rolls 10, 11, 12, 70, 13 and 14, 15, 16, 70, 17 respectively around which rolls, belts or band carriers pass in the manner to be described below. The framework also carries near its upper end the grooved guide-pulleys 18, 19, 20, 21,

Serial N0. 633,080.

two of which, namely 20, 21 are journaled in a small frame 69 that can move up and down in a guide-way not shown. A weight 71 is attached to a cord 72 that passes over a pulley 73 and is fastened to the small frame 69. The weight 71 produces enough tension to keep the belt or band tight at all times.

An endless band is used to carry the objects through the saturator. The parts that move in opposite directions are referred to by arrows so that their paths can be easily traced. Beginning at the pulley 19 in Fig. 4 it is seen that the belt 25 passes downwardly and then several times around the rolls 10, 11, 12, 70, 13 finally passing up over the pulleys 20 and 21. So far it has been on the inside path but as it passes over pulley 20, it starts on the outside path under the rolls l6 and 15, over the roll 14, under the rolls l1 and 12, over the roll 17 and again under roll 16 and so on for several turns, finally passing under roll 15 and back to pulley 19 where it started. It is to be understood that the parts of this endless belt are caused to travel in the directions indicated by the arrows and it will be observed that the portions of these belts that pass between the rolls 10 and 14 are moving in a downward direction, the portions that pass under the rolls 11 and 12 move toward the left and the portions passing from rolls 12 to 17 move upwardly at all times. In this way an object 27 to be carried beneath the surface of the liquid in the tank in which the framework carrying these rolls is placed, can be inserted between the rolls 10 and 14 and will be gripped by portions of the band on the opposite sides thereof and will be carried beneath the rolls 11 and 12 and over roll and finally discharged between the rolls 13 and 17.

In order to keep the endless band traveling in the directions indicated, a motor 30 (see Fig. 1) adjustable along the base 31 by means of the screws 32 drives a sprocket wheel 34 by means of the chain belt 33. The sprocket wheel 34 (see Fig. 3) carries a smaller sprocket wheel 35 concentric therewith. The upper rolls 13 and 14 are directly driven by the chain 37 which passes over the sprocket 35 and drives sprocket 38 on roll 13 and sprocket 42 on roll 14. The roll 17 is driven bya small gear 40 which meshes with gear 41, the latter being fastened to roll 13. These two gears 40 and 41 are on the opposite ends of rolls 13 and 17 from the sprocket chain 37 and sprocket 38. Gears 42 on roll 14 and 43 on roll 10 also mesh and cause rolls 10 and 14 to revolve in opposite directions. The sprocket chain 37 passes around the sprocket wheel 35, the sprocket 42, over the idler sprocket 45, which may be adjustable to take up the slack. The chain 37 also drives the rolls 13 by means of the sprocket 38. In this way the rolls 13 and 17 as well as the rolls 10 and 14 are kept revolving in opposite directions and cause the endless belt to travel as indicated. In case the band becomes loose or stretched, the slack is automatically taken up b the weight 71 which is fastened so as to raise the pulley 20 as indicated in Fig. 1. It will be observed that the pulleys 18 and 19 are near one corner of the framework and the pulleys 20 and 21 are near the diagonal corner so that the endless belt will be constantly guided to the proper points on the respective rolls. The rolls may be provided with grooves if desired, to keep the convolutions in place so the band may be guided where needed in any suitable manner.

The sprocket wheel is'carried by a roll of substantially the same length as roll 17 and the roll 45 revolves in the same direction as rOll 17. The roll 45 carries at its other end a gear 46 which meshes with a gear 47 carried by the roll 48 mounted above the roll 45. Saturated samples of roofing material discharged from between rolls 17 and 13 may, if desired, have the surplus saturant squeezed therefrom by being passed between the rolls 45' and 48 which may be made adjustable to and from each other.

I claim:

1. In a device of the character described, a saturating tank, means for carrying an object in a vertical direction into and out of the saturant in said tank and means for varying the depth to which said object can be carried into said saturant.

2. In a device of the character described, a saturating tank, means including a belt passing around an inner set of rolls and an outer set of rolls for carrying an object through the saturant in said tank to a variable predetermined depth and for a variable predetermined length of time.

3. In a device of the character described, a saturating tank, means including a belt passing around an inner set of rolls and an outer set of rolls for carrying an object through the saturant in said tank and means for varying the depth to which said object can be carried into said saturant.

4. In a device of the character described, a saturating tank, a band having parallel portions moving in the same direction and adapted to receive an object between said portions, said band passing into said tank.

5. In a device of the character described, a saturating tank, a band having parallel portions adapted to move in the same direction and adapted to receive an object between them, said band passing over rollers and means for varying the depth to which said band extends into said tank.

6. In a device of the character described, a tank, a carrier extending into said tank, said carrier comprising a belt passing around an inner set of rolls and an outer set of rolls, portions of said belt being spaced laterally from each other and moving in the same direction.

7. In a device of the character described, a saturating tank and a belt having parallel portions adapted to move in the same direction into and out of said tank, alternate parallel portions being adapted to grip an object to be saturated on either side thereof and conduct said object into and out of the saturating tank.

In testimony whereof I afiix my signature.
